[PMID 21934640] Test of association between 10 single nucleotide polymorphisms in the oxytocin receptor gene and conduct disorder.

[PMID 27497314] Variation in the oxytocin receptor gene (OXTR) is associated with differences in moral judgment. There was a significant negative association between the number of copies of the minor allele, T, and the frequency of utilitarian responses (β = −0.156, P = 0.019). In other words, participants homozygous for the C allele gave the most utilitarian responses, and participants homozygous for the T allele gave the fewest.
